BACKGROUND OF THE INVENTION [0001] 1. FIELD OF THE INVENTION [0002] This is a dental implant which is generally cylindrical and is not tapered. [0003] 2. DESCRIPTION OF THE RELATED ART BACKGROUND ART [0004] The occlusal force can be divided into vertical force and horizontal force. The vertical force for the implant is the compression force at the bottom and the shearing force at the lateral. The horizontal force is a tipping force for the implant. [0005] Since the horizontal force toward the proximal side is co-bolstered by the adjacent teeth (or implants), such force is less detrimental to the alveolar bone. The dental implant catches the bone to resist the occlusal force. Therefore, to have implants catch enough alveolar bone for the occlusal force, yet keep the alveolar bone from being destroyed is the basic and most important consideration for dental implant design. [0006] Since the advent of titanium dental implant, many dental implants have the shape of natural root lingered. But as a matter of fact, the supporting mechanisms of the natural tooth and that of the implant are not the same. The natural tooth is suspended in the bone by the ligaments, the implant is "fixed" to the bone. Mimicking the morphology of the root of the tooth does not make sense. Tapering of the implant would reduce the capability to resist the vertical force and the horizontal force. And as is seen clinically, the deeper portion of alveolar bone always has ample space for the implant. Another drawback for many contemporary implants is the threads or fins. The threads or fins are basically horizontal projection(s) from the cylinder. The horizontal projection(s) catch bone in such manners that they are significantly less equipped for horizontal forces than for vertical forces. This may explain why the successful rate of implant in the maxilla is always lower than that in the mandible. The implants in the maxilla receive more horizontal force than those in the mandible. [0007] Bicon (U.S. Pat. No. 4,738,623) FIG. 1a, a dental implant system considered by many dentists one of the best implant systems, also has the disadvantages mentioned above. Like other implant, the entrance to the bone is the most vulnerable. Bicon (FIG. 1a) deals with the problem seriously. According to it's manual, the Bicon's (FIG. 1a) implant is implanted 1 mm.about.2 mm below the alveolar crest. Later, some of the bone is removed, and the abutment and crown is connected to the implant. But as is clinically observed, in the long run the bone would retreat to the shoulder of Bicon's implant (FIG. 1a). Although the material of the implant and that of the abutment post are the same, the abutment post doesn't get osseointegrated. Maybe there is micro-rotation of the abutment post. An un-osseointegrated post in the bone is a highway for the hostile bacteria In some cases, the bony deteriorations continued, and the implant exposures were inevitable. The exposures were often on the horizontal-force-bearing side. Such exposure would embarrass the patient and leave an ordeal for the dentist. SUMMARY OF THE INVENTION [0008] The present invention of the dental implants pays more attention to the horizontal force that is usually ignored by the other systems. By the design of proximal plate-like projection(s) and clearances on buccal and lingual sides, the implant may deal with the force from occlusion more correctly. [0009] The proximal plate-like projection(s) catch more bone for the horizontal force and escape from most of the vertical force. The plate-like projection(s) arise from the cylinder toward distal or mesial direction. On the buccal and lingual sides at the level of the plate-like projection(s), there are no projection(s). Because the buccal and lingual bone plates are always thin and are also the weak points in dental implantology, the plates had better not to bear too much force. Continuing with the neck, the clearances and the neck provide more space for the bony plates and carry less force to the plates. The implant provides intact space for the thin plates that are not disturbed by any projection, and would help to meet esthetic demand because the chance of neck exposure is reduced. The implant effectively deals with the horizontal force by the plate-like projection(s) which are surrounded by ample bony structure. [0010] The neck had better to be as narrow as possible if it's mechanically approved. With such design the rim on the neck would be narrow. The rim toward the buccal side is trimmed to simulate the curvature of buccal gingival. The trimming begins from proximal sides downwardly to the buccal side. The trimming would allow the surgeon not to bury the implant deep in the bone without worrying the exposure of dental implant on the buccal side. And the trimming is likely to match the asymmetrically resorbed ridge. [0011] The bottom is dimpled. The bottom receives a lot of vertical force. The dimple disperses the pressure.
